scienceworld-threshold-evaluator

This skill compares a measured numerical value (e.g., temperature, weight) against a predefined threshold to determine a binary outcome. It should be triggered immediately after obtaining a measurement that has an associated conditional instruction. The skill evaluates if the value is above/below the threshold to guide the next action.

Threshold Evaluation Skill

When to Use

Trigger this skill immediately after you obtain a numerical measurement (e.g., temperature reading) and you have a conditional instruction that depends on that measurement (e.g., "If value > X, do A; if value < X, do B").

Core Logic

  1. Extract the Measurement: Identify the numerical value from the observation (e.g., "the thermometer measures a temperature of 56 degrees celsius" -> 56).
  2. Identify the Threshold & Condition: Parse the user's instruction to find the threshold value and the comparison operator (e.g., "above 50.0 degrees" -> threshold=50.0, operator=">").
  3. Evaluate: Perform the comparison (measured_value > threshold or measured_value < threshold).
  4. Execute Branch: Based on the boolean result, perform the corresponding action specified in the instruction.

Key Principles

  • Immediate Execution: Do not perform any other actions between obtaining the measurement and running this evaluation.
  • Precision: Use the exact numerical value from the observation. Do not estimate or round unless specified.
  • Binary Decision: The outcome is strictly one of two paths. If the measurement equals the threshold, re-examine the instruction for guidance (e.g., "above" typically means >, not >=).

Common Pitfalls (from Trajectory)

  • Incorrect Branching: Do not execute the branch for the opposite condition (e.g., focusing on the blue box when the value is above the threshold).
  • Premature Evaluation: Ensure the measurement is complete and valid before evaluating.
  • Action Confusion: The final action (e.g., focus on OBJ) must target the correct object specified for the satisfied condition.
